Mark the mismatched pair (w.r.t deficiency symptoms)

Options

A. Necrosis - K,Cu,Ca,Mg
B. Delay flowering - Ca,Mg,K
C. Inhibition of cell division - Mo,N,S,K
D. Chlorosis - N,K,Mg,S,Zn

Answer

To find the mismatched pair with respect to deficiency symptoms, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand Necrosis**:
- Necrosis refers to the death of tissue.
- It is primarily caused by deficiencies in calcium, magnesium, copper, and potassium.
- **Conclusion**: This option is correctly matched.

2. **Analyze Delay in Flowering**:
- Delay in flowering is typically associated with deficiencies in nitrogen, sulfur, and molybdenum.
- However, sodium is not commonly linked to this symptom.
- **Conclusion**: This option is mismatched.

3. **Examine Inhibition of Cell Division**:
- Inhibition of cell division can be caused by low levels of nitrogen, potassium, sulfur, and molybdenum.
- **Conclusion**: This option is correctly matched.

4. **Review Chlorosis**:
- Chlorosis is characterized by the yellowing of leaves due to the loss of chlorophyll.
- It is caused by deficiencies in nitrogen, potassium, magnesium, sulfur, and zinc.
- **Conclusion**: This option is correctly matched.

### Final Answer:
The mismatched pair with respect to deficiency symptoms is **Delay in Flowering**.
